maybe not removed, but they certainly did make breaking changes to the language. here are some of the most obvious

python 2:

  print "foo"   # foo
  3 / 5         # 0
  apply         # <built-in function apply>

python 3:

  print "foo"  # SyntaxError: Missing parentheses in call to 'print'
  3 / 5        # 0.6
  apply        # NameError: name 'apply' is not defined
